摘　　要：对高压重要母线需装设母差保护,母差保护配置趋势是双母线配双微机母差保护,现阶段微机母差保护主要采用复式比率差动原理并具有良好性能。母差保护新建和改造需要注意电流、电压及刀闸位置开入回路并进行向量测试,保证母差保护正确可靠运行。The high voltage important bus must install bus protection, the configure direction is double digital protect for double bus, bus protection mostly use double-entry rate differential elements, and it have favorable capability. We must advert incoming circuits of current, voltage.knife switch position when we compose or rebuild bus protection, in addition we must test the vector, so we can assure the accurate and reliable function of bus protection.
